Abstract

PURPOSE:To easily change a ceiling level and form a skip floor, by forming an external steel frame beam in a skeleton construction through double arrangement of specified rating steel frames by heaping them up vertically. CONSTITUTION:In a skeleton construction with external wall plates 3 fitted to a framework consisting of steel frame columns 1 and steel frame beams 2, the external steel frame beams 2 corresponding to the outer periphery of a structure are formed with double arrangement for heaping up the steel frames of a specified rating vertically. Then, the level H of room ceiling plates 4 surrounded with the double steel frame beams 2 can be made higher than a normal ceiling level L, and so the ceiling level can be easily changed and a skip floor can be easily formed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an architectural frame structure that allows the ceiling height to be easily changed or a skip floor to be constructed in mass-produced buildings such as prefabricated buildings.

[Conventional technology]

In conventional mass-produced buildings, it is desirable to have some modules with the dimensions of each member set to a predetermined standard, and to reduce the number of types of parts as much as possible. Therefore, the applicant's residential construction also uses steel columns.

In the structure where ALC boards are attached from the beam to the frame, the ceiling height H is usually 2400 mm, the thickness (D) of the ALC board for the external wall is 75 m5, and the support span (L) of the ALC board is 35D. It is designed to be.

[Problem to be solved by the invention]

However, depending on the needs of consumers or to make homes more upscale, the ceiling heights of some rooms may be increased, or steps may be provided between rooms, that is, skip floors may be created. Pillars for that.

If the cross-section of the beam and other dimensions are increased, the prefabricated members will not fit well, such as causing problems in installing the external wall panels. For example, if the cross section of the beam is increased, the beam flange will become larger and protrude from the column surface, which will hinder the installation and fitting of exterior wall panels. Also, if the column height is increased, the ALC
The thickness D of the plate is 100InI11, which increases the overall load and changes the wall thickness, so the connector to which the ALC plate is attached has to be changed significantly, which increases the cost and is not practical.

[Means to solve the problem]

This invention was developed with the aim of solving the above-mentioned problems, and includes a steel frame column of a predetermined standard.

It is a frame structure in which beams are used as a frame and external wall panels are attached to the frame.It is an architectural frame structure in which beams of a specified standard are placed double over the steel beams of the outside street, which corresponds to the outer periphery of the building. .

〔Example〕

The steel columns 1 and steel beams 2 that make up the framework are members of a predetermined standard, and in principle, members with a constant cross-section are used for the building as a whole. Square steel pipes, H-shaped steel, etc. are used for the steel frame column 1, and H-shaped steel, etc. are used for the steel beam 2.

The outer wall board 3 is made of ALC board or the like and has a predetermined thickness, for example, 7.
The thickness of 5 kaku is used.

To explain the case where you want to increase the ceiling height, firstly, the steel beams 2 on the outside are arranged in a double manner by stacking beams of a predetermined standard, that is, beams with the same cross section, one above the other. The height H of the ceiling board 4 in the room surrounded by the double steel beams 2 is set to a normal standard size, for example, the ceiling height of 2400 mm can be changed to about 2600 to 2700 mm. Further, the vertically stacked steel beams 2 are appropriately tightened at their flanges with bolts 5 or the like. The outer wall board 3 is connected to the steel beam 2 using hook bolts 6, angles, etc. Further, a covering metal plate 7 is attached to the outside of the upper steel beam 2. The ceiling plate 4 is installed in a position above the lower steel beam 2. 8 is the upper floor ALC board. 9 is out of line.

The pillars 10 and braces 11 on Nakadori (Fig. 2) are the same in cross section as the steel columns 1 and braces 9 on Sotodori, but are longer in length.

Furthermore, if a skip floor structure is desired, if a floor is provided even at the height of the lower steel beam, a step will be created in the floor at the part where the floor is provided at the height of the double steel beam, so a skip floor can be used.

〔Effect of the invention〕

This invention consists of the above-mentioned structure, and when the need arises to raise the ceiling height higher than usual, it can be handled by doubling the beams of a predetermined standard, and the support span of the external wall is the same as in the normal case. , The same thickness as other parts can be used, and the function as a mass-produced building is not impaired.
